husbands back and forth

So my husband and I have been ttc since august we got married in February of this year. He had a work injury and has been out of work for almost two months and his drinking has gotten worse and worse. When he's sober we are fine great amazing but when he drinks it's terrible he wants a divorce he doesn't want kids he just doesn't care and it's every other day. I'm stressed I don't make enough money to support everything we have or need he's working on getting back to work but I feel like his drinking isn't letting him. I've tried being supportive and helpful but there's only so much I can do.. I guess I'm venting but I guess I just need help because I'm scared of bringing a baby into this world with his problem. But I also feel on nights when he's drinking I'll have a piece of him with me and i don't know. Any advice or tips someone can give?
